Application filed March 9, 1917. Serial No. 153,560.

To all whom it may concern:

Be it known that I, LEE SUMNER Trroarr- SON, a citizen of the UnitedStates, residing in the borough of Brooklyn, city of New York, county ofKings, and State of New York, have invented new and useful Tmprovementsin Machines for Dyeing Hanks ratus, the cover being shown raised indotted lines;

Fig. 2 is an end view thereof;

Fig. 3 is an enlarged fragmentary view of one of the wheel spokes and aportion of a supporting ribbon secured thereto;

Fig. 4: is a section on the line M of Fig. 3;

Fig. 5 is a face view of a portion of a single ribbon;

Fig. 6 is a face view of a portion of a composite ribbon;

Fig. 7 is a longitudinal section through a portion of such compositeribbon;

Fig. 8 is a face view of the other member of this ribbon;

Fig. 9 is an enlarged semi-diagrammatic view of one of the wheels withribbons thereon in concentric circles;

Fig. 10 is a similar view of a wheel with the ribbons arranged inspirals; and

Fig. 11 is a semi-diagrammatic view showing a way of supporting hatbodies or the like.

A pair of upright wheels 2 and 2 which in practice may be about six feetin diam eter, are mounted upon a driven axle 3 with their lower portionsinside a vat 4:. The spokes 5 and rims 6 should be of some material, forexample brass, having suitable strength and resistant to chemicals andsteam, while the hubs 7 and the axle which are above the liquid levelmay be of iron. The material to be dyed is supported upon and betweenthese Wheels, and, in order to accommodate hanks of different sizes orcloth of various widths, provision is made for changing the distancebetween them. To this end the axle is formed with a keyway 8accommodating akey 9 in the hub of the wheel 2, so that this wheel mayhe slid along the shaft and set at any desired point by means of a screw10. The other wheel preferably occupies a fixed position. The axle turnsin bearings 11 upon standards 12 at opposite sides of the tub, runningdown to a firm foundation. The axle bears two sets of pulleys, one beinga low speed drive pulley l3 and a corresponding idler 14:, and the othera high speed drive pulley 15 and corresponding idler 16. I

The means whereby the material is supported between the wheels-comprisesflexible metal ribbons 17 or 17, of brass or the like, which are carriedat the inner sides of the wheels encircling the axle at variousdistances therefrom, their arrangement being similar upon the twowheels.

. The mountings for these ribbons preferably comprise right-angular hookbolts 18, the shanks of which are screwed into threaded openings in thespokes and locked by nuts 19, the hook ends 20 being turned outward awayfrom the axle and substantially parallel with the planes of the wheels.The ribbons are formed with openings 21 at intervals, which take overthese hook ends. WVing nuts 22 have screw-threaded enga ement with thesaid ends for holding the ribbons firmly in place.

The single ribbons 17 are designed more particularly for thodyeing ofhanks,through the ends of which the ribbons are passed, as indicatedschematically in 1* i2. 2. When the single ribbons are used the arepreferably disposed in concentric circles, as shown in Fig. 9, and itwill be understood that each circle mav be composed of a number of sections overlapped at their ends. This is indicated in connection with theoutermost ribbon of Fig. 9.

For dyeing cloth a double ribbon is employed, of which the members 17and 17 have openings 21 as before; and in addition the member 17 isprovided with pins 23 and the ribbon 17 with corresponding apertures 24.The marginal portions of the clothare impaled upon the said pins, heldagainst slipping off them by the ribbon 17, and the composite structureis held together and secured in place upon the wheel by means of thehooks and wing nuts 18 and 22 just described. For cloth dyeing this formof ribbon is preferably arranged spirally about the wheel axle, as shownin Fig. 10, and, as before, the ribbon may be divided lengthwiseintosections of convenient length.

In order to adapt the wheels for either style and arrangement of ribbon,it is desirable to provide their spokes with screwthreaded openings forthe shanks of the hook bolts lying both in concentric circles and in aspiral.

An arched cover 26, hinged at 27 at one end, fits over the vat to keepheat, when drying, and steam, when dyeing, from escaping. This cover hasan outlet 28 in the top to allow steam and moist hot air to escape tothe exhaust pipe 29, and is also provided with a lateral openino 30 toadmit hot dry air led from a suitable source through piping 31 to thespace above the liquid in the vat. Connection is established betweensaid entrance. and outlet and the corresponding pipe by means of slidingmembers 32 and 33, which can be readily slipped out of the way to permitthe cover to be raised.

A pipe 3st for the supply of water or chemicals discharges into theupper part of the vat; and steam piping enters at the top, descendswithin the vat, and extends with perforations over the bottomsubstantially throughout the length of the vat to secure even boiling.The top is also provided with a direct connection 36 to the sewer, witha suitable plug 37 for opening and closing the same.

After the wheels have been loaded and the liquid introduced into thevat, the machine is set in motion by shifting the low speed band ontothe low speed pulley, a speed in the neighborhood of ten revolutions perminute being preferred for dyeing. \Vhen the dyeing is finished theliquid is run off, fresh water admitted, and the material rinsed byrevolving the wheels therein; then the water is allowed to escape, andthe machine is thrown into high speed, causing it to act as a centrifual extractor. At the same time hot air is blown directly on the stock,thus hastening the drying. For drying a speed of one hundred revolutionsper minute is desirable.

Vhile a pair of wheels is spoken of, it will be understood that thecapacity of the machine may be increased by placing another adjustablewheel on the other side of the fixed wheel, the inclosure beingcorrespondingly increased in width.

For dyeing hat bodies or other articles, demountable bridges 38 may becarried from wheel to wheel or from ribbon to ribbon and suitablysecured, and the objects attached thereto by hooks, or otherwise, asdiagrammatically represented in Fig. 11.

That I claim as new is:

v 1. A dyeing and dryin machine comprising a vat, a pair of wheelstherein upon a rotatable axle, and means for supporting the material onand between the wheels comprising curved ribbons mounted at the innersides of the wheels.

2. In a dyeing and drying machine, the combination of a pair of wheelsupon a rotatable axle, and means for supporting the material on andbetween the wheels comprising curved ribbons encircling the axle atdifferent distances therefrom at the inner sides of the wheels, andhooks on the wheel spokes wherewith the ribbons are engaged.

3. A dyeing and drying machine, comprising a vat, a pair of wheelsthere-in upon a rotatable axle, means whereby relative adjustment may beproduced between the wheels lengthwise of the axle, and means forsupporting the material on and between the wheels comprising curvedribbons mounted at the inner sides of the wheels.

4. In a dyeing and drying apparatus, the combination of a pair ofconnected wheels, and means for supporting the material on and betweenthe wheels comprising double ribbons, of which one member is providedwith pins and the other with corresponding openings, and means formounting the ribbons at the inner sides of the wheels.

Dated this 1st day of March, 1917.
